17.10 Transfer of Unbalanced Moments to Columns 661<br />

Figure 17.26 Shear stresses due to V u<br />

and M.<br />

assumed to be acting around a periphery plane located at a distance d/2 from the face of the column<br />

[16], as shown in Fig. 17.26. The equation for computing the shear stresses is<br />

where<br />

v 1,2 = V u<br />

A c<br />

± M vC<br />

J c<br />

(17.27)<br />

A c = area of critical section around column<br />

J c = polar moment of inertia of areas parallel to applied moment in addition to that of end area<br />

about centroidal axis of critical section<br />

For an interior column,<br />

A c = 2d(x + y) (17.28)
